Preventing food poisoning at home takes just a few simple steps; but abroad, it’s a little trickier to stay safe. Food that isn’t prepared properly or is exposed to dirty water or unclean surfaces can harbor foodborne bacteria such as E. coli, salmonella, or cyclospora. Ensure that the food you eat is served hot, that the food is fresh and cooked to order, and that it is prepared in a clean restaurant. Look out for signs that the restaurant is unclean. Additionally, be wary of salads that may have been rinsed in untreated water and food that’s been left out for long periods of time, such as from a buffet.
